Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner in which condensed water discharged from an indoor unit during cooling / dehumidifying operation is used for cooling electric components of an outdoor unit.

[0002]

2. Description of the Related Art In a conventional air conditioner indoor unit, condensed water discharged from an indoor heat exchanger during a cooling / dehumidifying operation is collected in a drain pan below the heat exchanger, and is discharged outside by a drain recovery pipe. It is being discharged. The temperature of the discharged condensed water is about 5 ° C. to 10 ° C., which is very cold. However, in the above-mentioned prior art, the condensed water flows along a refrigerant pipe with a drain hose and is discarded outside as it is. When the outdoor unit was installed above the indoor unit, a drain hose was provided separately from the refrigerant pipe, and the drain hose was used to drain the water downward.

[0003] In addition, since the electrical components of the outdoor unit are integrated and compacted, and are controlled with a large current by using an inverter, a large amount of heat is generated in the compressor, the reactor, the power transistor, the diode, and the like. . In summer, when the cooling operation is performed, the outdoor temperature rises to about 35 ° C., and the installation portion may be located above the compressor. It will be about 50-60 ° C. In such an ambient temperature, the temperature of the above-mentioned heat-generating component rises to about 80 to 100 ° C. due to its own heat generation. In order to cope with this, conventionally, the heat-generating component of the electrical part is closely attached to the aluminum finned radiator plate, the fin part is arranged at the position where the wind of the outdoor unit fan passes, and it is cooled by ventilation, and the electrical part is cooled. I try to lower the temperature.

[0004] As shown in Japanese Utility Model Application Laid-Open No. 6-59728, a slit is provided in a part of the outdoor unit so that air is circulated in an electric box and the electric part is cooled by the outdoor air. Was. However, even in this method, a heat radiating plate must be provided in the heat generating portion and cooled by an outdoor unit fan.

In the window air conditioner disclosed in JP-A-1-306743, condensed water generated in the indoor heat exchanger during cooling operation is stored in a condensed water reservoir provided at the bottom of the air conditioning body. This condensed water is used to cool the radiation fins of the outdoor electrical unit. Therefore, although the cooling effect is improved, it is necessary to prevent moisture from entering the electrical components, and it is difficult to arrange the electrical components with other electrical components. This conventional technique does not disclose any specific technique for solving these problems. In addition, there has not been reported any example in which such a technology is applied to a separate type air conditioner including both an indoor unit and an outdoor unit.

[0006]

However, the above-mentioned conventional air conditioner has the following problems. In the cooling means of the prior art, when the outside air temperature in summer is about 3
Since the temperature is about 5 ° C., the temperature of the wind passing through the electrical components is high.
Therefore, there is a problem that a sufficient cooling effect cannot be obtained. In addition, cooling of electrical components that generate heat is often performed by an outdoor unit fan when the temperature rises in the summer, but the blowout temperature of the outdoor unit fan also falls from about 40 ° C. to about 45 ° C., so that the cooling effect by ventilation is also the same. It was not enough. On top of that, the radiator plate of the electrical components installed in the ventilation area of the outdoor unit hinders the smooth ventilation of the outdoor unit, generating abnormal noise, reducing the air volume performance, and installing the fan that does not contact Had various issues such as the choice of

[0007] In addition, electric components that generate heat on the outdoor unit side have conventionally been arranged so as to be separated or separated from components that do not contribute to heat generation. However, the recent compactness of electrical components
The amount of heat generated by electrical components generated by integration is increasing. Therefore, components that contribute to heat generation and a heat radiating plate are arranged near components that do not contribute to heat generation, and the heat affects components that do not take part in heat generation. Failure often occurs due to temperature rise due to heat radiation.

There is also a method in which a slit or the like is provided in the outdoor unit and the electric part of the outdoor unit is directly cooled by ventilation, but a closing failure occurs due to suction of dust, dust, sand, soil and the like in the slit portion, and cooling by ventilation is performed. May not be possible. In addition, in order to prevent rainwater from flowing into the slit provided in the ventilation path of the fan of the outdoor unit, there is a great limitation in selecting the installation location of the outdoor unit.

Embodiments of the present invention will be described with reference to the drawings. In each embodiment, corresponding parts are denoted by the same reference numerals, and description thereof will be omitted.

FIG. 1 is a configuration diagram of the entire air conditioner. The indoor unit 1 and the outdoor unit 2 are connected by a refrigerant pipe 3. The condensed water discharged from the indoor unit 1 is discharged outside by the drain hose 4.

FIG. 2A is a top perspective view of a main part of a general outdoor unit 2, and FIG. 2B is a perspective view showing a configuration of a conventional heat radiating device of the outdoor unit. As shown in these figures, when the outdoor unit 2 is operated, the blower 7 is operated, the outside air is taken in from the slit 36 provided in the outdoor unit 2, and the intake air flows 37 and 38 come into contact with the radiation fins 6 ′, Electrical box 5
The heat-generating component 8 provided therein is cooled. FIG.
In (b), 27 is a heat exchanger for an outdoor unit, 33 is a compressor, and 35 is a ventilation path provided in the electrical box 5.

<Embodiment 1> FIG. 3 shows a configuration of a main part of a first embodiment of the present invention. According to this embodiment, the condensed water inflow port 9 of the condensed water flowing out of the outdoor unit 1 is provided in the outdoor unit 2, and the condensed water is guided to the radiation fins 6 ′ of the heat generating component 8 provided in the outdoor unit 2. . In FIG. 3, 5
Is an electrical box, 7 is a blower on the outdoor unit side, 10 is an electrical drain hose of the outdoor unit, 13 is a reactor, 14 is a compressor cover around the compressor, 15 is a flow control valve, and 16 is a blower chamber of the outdoor unit And a shielding plate that separates the machine room.

The temperature of the condensed water flowing out during the cooling and dehumidifying operation is about 5 ° C. to about 10 ° C. The condensed water flowing out of the indoor unit 1 is supplied to the electric equipment box 5 through the condensed water inlet 9 of the outdoor unit 2.
To the heat dissipating fins 6 ′ of the electrical components attached to the device. The temperature of the heat-generating component 8 in the electrical component box 5 is about 80 to 110 ° C. when there is no cooling effect, so that the component is destroyed in a normal environment and malfunctions. Even when the radiation fins 6 ′ are provided and the blower 7 on the outdoor unit side is in a ventilation state, the temperature of the heat-generating component 8 in the electrical equipment box 5 is about 70 to 90 ° C. Further, the radiating fins 6 ′ and the heat-generating components 8 of the electrical component that radiate heat are interposed through the electrical component box 5.
Alternatively, it is directly connected via a hole provided in the electrical component box 5, and the radiation fins 6 'and the electrical component box 5 are sealed so that the inflow of moisture does not occur.

The condensed water that has flowed into the outdoor unit 2 absorbs the heat generated from the heat-generating component 8 of the electrical unit by the radiating fins 6 ′ of the outdoor unit 2 and passes through the electrical unit drain hose 10 of the outdoor unit 2. It is discharged to the outside from the drain discharge port provided in 2. At the start of the cooling operation, the condensed water from the indoor unit 1 does not flow out much, but the temperature of the heat generating component 8 of the electrical unit at the start of the operation is also low. Heating parts 8 for about 1 hour from the start of operation
However, in this state, condensed water is flowing. Therefore, even if there is no inflow of condensed water at the start of operation, no trouble occurs due to a rise in the temperature of the heat generating component 8.

<Embodiment 2> A second embodiment of the present invention will be described with reference to FIGS. This second embodiment is shown in FIG.
As shown in (a), the heat radiating plate 6 of the heat generating component 8 of the electrical unit on the outdoor unit side is installed so as to be in contact with the condensed water reservoir 11, and the indoor unit 1
Of condensed water flowing out from the outdoor unit 2
1 to promote heat radiation of the heat generating component 8. In addition, as shown in FIG. 5A, a heat radiating fin 6 ′ may be provided on the condensed water reservoir 11 side instead of the heat radiating plate 6 to cool the heat generating component 8. 4 (b) and 5
(B) is a diagram showing how to attach the heat-generating component 8 to the condensed water sump 11 of the outdoor unit 2. It is attached so that. Condensed water reservoir 11
, Low-temperature condensed water flows from the indoor unit 1 as the cooling / dehumidifying operation time elapses. The condensed water in the condensed water reservoir 11 is heated by absorbing heat from the heat-generating component 8, convects above the condensed water reservoir 11, and flows out of the outdoor unit 2 through the drain port 12. Here, 34 is a connecting line connecting the indoor unit 1 and the outdoor unit 2, and 30 is a terminal plate.

<Embodiment 3> A third embodiment of the present invention will be described with reference to FIG. In this embodiment, unlike the second embodiment, the surface of the radiating fins 6 'is covered with an absorbent 18 of condensed water, for example, polyurethane or polyethylene, and the absorbent 18 absorbs the condensed water to thereby generate the heat generating component 8. Is cooled. Embodiments 1 and 2 above
, The condensed water discharged from the indoor unit 1
In the third embodiment, low-temperature condensed water is absorbed by the absorber 18, and the heat is released only by passing over the radiating fins 6 ′ in the electrical box 5. Since the cooling is performed so as to surround the fins 6 ′, the cooling of the heat generating component 8 can be performed more efficiently. That is, since the condensed water spreads evenly on the absorber 18 on the radiating fins 6 'and cools so as to entirely cover the radiating fins 6' of the heat generating component 8, the cooling effect can be further enhanced. . When the moisture absorber 18 is air-cooled by the blower 7 on the outdoor unit side, the effect of heat of vaporization further increases the cooling effect. Condensed water is the absorber 1
When the amount of water absorbed exceeds 8, the water overflows, and condensed water does not accumulate excessively.

<Embodiment 4> A fourth embodiment of the present invention will be described with reference to FIG. In the fourth embodiment, the condensed water reservoir 11 is installed above the radiating fin 6 ′, the water distribution pipe 17 is provided in an opening provided at the bottom of the condensed water basin 11, and the radiation fin 6 ′ is provided at the tip of the water distribution pipe. The drain nozzle 19 is installed according to the surface. With this configuration, the condensed water can be widely and uniformly discharged to the radiation fins 6 ′, and the cooling effect of the heat-generating component 8 can be further improved. Further, since the condensed water reservoir 11 is provided above the electrical equipment box 5 of the outdoor unit 2, the condensed water that has flowed out can be stored, and it is possible to prevent the water from being discharged all at once.
The water distribution nozzle 19 may be a jolo-shaped one in which a plurality of holes are opened in an arc shape facing the radiating fin 6 ′, or may be a one provided with a plurality of holes in a straight line. The condensed water reservoir 11 can be made of sheet metal or resin. However, since the temperature difference between the inside of the outdoor unit 2 and the condensed water reservoir 11 is remarkable, the condensed water reservoir is prevented from dropping due to dew on the inner wall of the outdoor unit. It is necessary to provide sufficient heat insulation between 11 and the inner wall of the outdoor unit.

<Embodiment 5> A fifth embodiment of the present invention will be described with reference to FIG. The fifth embodiment is different from the fourth embodiment in that the water distribution pipe 1 provided at the bottom opening of the condensed water reservoir 11 is provided.
An electromagnetic valve 20 is provided in the middle of 7 so that the flow rate of the condensed water can be adjusted according to the temperature of the radiation fin 6 ′ provided on the heat-generating component 8. The flow rate is adjusted by detecting the temperature of the radiation fin 6 ′ by a temperature sensor 21 such as a thermistor provided on the back surface of the radiation fin 6 ′, and opening the electromagnetic valve 20 when the detected temperature reaches a predetermined temperature. Is going. The predetermined temperature in this case varies depending on the model of the heat-generating component 8, but is about 60 to 80 ° C.
The temperature is set at a point beyond the optimum control temperature of the heat generating component 8.

Since the condensed water drained from the indoor unit 1 from the start of operation is stored in the condensed water reservoir 11, when the temperature of the radiating fins 6 'rises, the temperature of the radiating fins 6' is reduced. It is enough. There is a method of controlling the solenoid valve 20 to open and close by increasing the surface temperature of the radiating fin 6 ′. As another method, a valve capable of linearly adjusting the degree of opening and closing from fully closed to fully open, such as a flow rate adjusting valve. Can also be used. In this case, the opening degree of the flow control valve is adjusted by increasing the temperature of the radiating fins 6 ′, and the temperature of the radiating portion can be maintained at an optimum value, so that the performance of the heat generating component 8 can be sufficiently exhibited. Become.

In this embodiment, the valve is controlled by detecting the surface temperature of the radiation fin 6 'by the temperature sensor 21 as described above. Temperature, that is, the temperature of the heat-generating component 8 is often determined by the control of the operation of the air conditioner. The solenoid valve 20 or the flow control valve can be controlled by the operating current value, the outside air temperature thermistor and the operating frequency of the compressor. It is desirable that the solenoid valve 20 and the flow control valve be fully opened at the end of the operation so that no condensed water remains in the condensed water reservoir 11. This is to prevent condensed water from remaining in the condensed water reservoir 11 when the operation is switched from the cooling operation to the heating operation. Condensed water reservoir 11
If condensed water remains, the outside air temperature is extremely low during the heating operation in winter, and the condensed water reservoir 11 may be broken by being frozen in the condensed water reservoir 11.

<Embodiment 6> A sixth embodiment of the present invention will be described with reference to FIG. In the sixth embodiment, an overflow pipe 22 for preventing overflow is provided inside or above the condensed water reservoir 11 of the fifth embodiment. With such a configuration,
When the amount of condensed water flowing into the condensed water reservoir 11 reaches a predetermined amount or more, the excess amount is drained to the outside via the overflow pipe 22, and the condensed water reservoir 11 does not accumulate more than the predetermined amount. Therefore, even if the solenoid valve 20 is kept closed, it is possible to prevent a water leakage accident due to condensed water.

The overflow discharged from the condensed water reservoir 11 to the outside through the overflow pipe 22 is combined with the condensed water discharged after cooling the radiation fins 6 'in the fifth embodiment. Thus, the heat exchanger 27 is guided to the upper part of the heat exchanger 27 provided in the outdoor unit 2 through the induction water passage 28 to directly cool the heat exchanger 27. With this configuration, the outdoor unit 2
Can be effectively cooled, and the efficiency of the outdoor unit 2 can be improved.

<Seventh Embodiment> A seventh embodiment of the present invention will be described with reference to FIG. Generally, an outdoor unit of an air conditioner 2
Is often installed below the indoor unit 1. However, due to recent housing circumstances, the number of cases where the outdoor unit 2 is hung on a wall or installed on a roof is increasing. If the outdoor unit 2 is installed above the indoor unit 1, in each of the above embodiments, condensed water cannot be supplied to the outdoor unit 2 provided above, and the outdoor unit 2
Can not use condensed water in In the present embodiment, the condensed water generated in the indoor unit 1 is guided to the condensed water reservoir 23 provided outdoors by the drain hose 4, and the condensed water stored in the condensed water reservoir 23 is supplied to the indoor unit 1 via the drain hose 4 by the water supply pump 24. Water is pumped to the outdoor unit 2 installed above. The condensed water pumped to the outdoor unit 2 may be supplied directly to the radiating fins 6 'of the heat-generating component 8 of the electrical unit as shown in the first embodiment, or as shown in the third embodiment. You may make it supply to the water supply body 18, and may make it supply it to the condensed water reservoir 11 as shown in said 2, 4, 5, 6 embodiment. Then, the condensed water pumped to the outdoor unit 2 is supplied to the heat-generating component 8 of the electrical component in the same manner as in the first to sixth embodiments.
Is cooled.

When the condensed water is pumped into the condensed water reservoir 11, a float switch for preventing the condensed water from being supplied to the heat-generating component 8 until the condensed water is sufficiently pumped into the condensed water reservoir 11 may be provided. The water supply pump 24
Is supplied from a commercial power supply, but a solar cell 26 with a rechargeable battery may be used as an alternative. In this case, extra power consumption by the commercial power supply for pumping can be suppressed. In FIG. 10, reference numeral 25 denotes an installation table provided on the roof.

<Eighth Embodiment> An eighth embodiment of the present invention will be described with reference to FIGS. In this embodiment, the top surface of the outdoor unit 2 is gently inclined toward the condensed water reservoir 11 for storing the condensed water from the indoor unit 1, and rainwater falling on the top surface of the outdoor unit 2 is provided on the top surface. From 31, the water is collected in the condensed water reservoir 11. The condensed water from the indoor unit 1 is collected in the condensed water reservoir 11 as in the case of the second, fourth, fifth, sixth and seventh embodiments. Therefore, the condensed water and the rainwater collected in the above-mentioned condensed water reservoir 11 are radiated by the heat radiating plate 6 and the heat radiating fins 6 ′ of the electrical unit.

A valve 29 for preventing infiltration of rainwater into the water is provided, and the valve 29 can be opened and closed according to the temperature around the outdoor unit 2.
That is, if the ambient temperature becomes extremely low in winter or the like, there is no need to cool the outdoor unit with rainwater, and an accident may occur if rainwater freezes. In such a case, the valve 29 is closed to prevent the inflow of rainwater and prevent an accident due to freezing of rainwater. That is, when the air conditioner is operating in the cooling or dehumidifying mode, the valve 2
